Overclockability has been a key selling point of the ATI Radeon 9600XT over the last 10 months. The card has a great amount of overclocking headroom, and since the Radeon X600 XT is essentially the same card under the hood, we expected it to be a decent overclocker as well. Our results weren't disappointing; we were able to get an overclock of 60MHz from the core and 50MHz from the memory of the Radeon X600 XT, giving us a final core speed of 560MHz and memory speed of 840MHz.
